More coded messages. Bel asked me for more codes, so I grabbed some facts for kids and encoded them online. If you want your child to learn more about Caesar cipher, we did an activity about it.
If your child is having trouble decoding, you can help by asking him/her if he/she knows any word that is just one letter. Then encourage him/her to try the possibilities. The last set is harder because there is no one-letter word so it might be a good idea to write down the two-letter words and see if he/she can figure some of them out.
